Thanks David. You explained this perfectly for me and I now have got the 710 working as it should. Regarding the aprs mode, I understand that I am only able to read packets but cannot transmit. The only way to transmit is to use the packet12.

Re: [TMD700A] How to use internal tnc D710GA
The serial connection on the back of the main radio body of a D710 is for programming the memories of the radio, to be used with Echolink, and also use the working-but-not-Kenwood-supported CAT control. It's the connector on the back of the D710 head that is used for packet work.
Once you connect to the D710's head, use a serial terminal program like say Putty running at a serial speed of 9600bps, 8 data bits, 1 stop bit, no parity, tap the lower right soft-key on the D710's control head labeled "TNC" until the Upper left of the display says "PACKET12". At that point, you should see the TNC boot up in your serial terminal program. That will prove that things are at least talking. From there, you can start configuring your APRS program. It's also worth mentioning that the D710 has it's own internal APRS functionality that's enabled by putting the TNC into "APRS12" mode using the "TNC" soft-key mentioned above.
If your interested in trying classic packet as well, I have a cheatsheet below:

I have just obtained a D710GA and am trying to use the internal tnc to do aprs. Can someone help me with how to connect the radio to the computer which runs my aprs software? I have the kenwood provided serial cable that plugs into the 9 pin mini din on the back of the main body of the radio (not the control head). When I tune the radio, I can hear the packets coming in but nothing shows up on the computer. I have activated the internal tnc and tried it in both aprs mode and packet mode with no difference. I am able to connect an external tnc to the data port and that works fine.
Thanks in advance
